AirJet® Cherry Grader

Description:

The AirJet® sorting system is the most technologically advanced cherry grading machinery on the market. The line features three types of AirJetTM Vision cameras – full HD, black and white, and near infrared (NIR) cameras. The grading machinery captures 21 images of the fruit surface, allowing inspection of more than 90% of the surface of each fruit. The machine enables sorting according to:

• Size – the dimensions of each fruit are calculated based on 21 optical camera images;
• Softness/firmness – the machine is able to separate cherries into 5 standard softness categories: intended for freezing, semi-soft, semi-hard, hard and extra-hard, and others, allowing producers to adjust the quality of fruit for sale to different markets and according to the individual requirements of their customers; 
• Defects – the AirJetTM Vision’s GPJ technology detects internal and external defects in fruit, such as bruising, discolouration and dryness, and other defects caused by various weather conditions; 
• Colour – the AirJet® sorting system can reject red, green, and underripe fruit.

The AirJet® system from GP Graders sorts cherries at the rate of up to 30.2 units per second per line, thus providing extremely high throughput while maintaining sorting accuracy.

Features and advantages

• Sorting is based on live feedback from AirJet Vision high definition (HD), black and white, and NIR cameras
• The grading machinery divides fruit into at least 5 softness categories, i.e. very soft (IQF), semi-soft, medium, semi-hard and hard
• The grading machinery detects damage and defects, such as bruises, cuts, cracks, scars, overmature fruit, and others, which can be defined using open source software
• Designed with food grade materials for quick rinsing and washing after use
• A simple and intuitive system operation interface
• A reduced number of seasonal employees working on the line, which translates into savings
